IMPRQVEMENT IN STREET-CAR AXLE-BOXES.

Specification forming part of Letters Patent No. 133,073, dated November12, 1872.

To all whom it may concern:

Be it known that I, ANDREW WIGHT, of

the city and county of St. Louis, and State of Missouri, have invented acertain Improvement in AXlG-BOX6S of Street-Cars, of which the followingis a specification:

My invention consists in forming the case of the axle-box with a chamberthat contains a dust-shield capable of moving vertically andhorizontally with the axle. The shield is made preferably of wood, andis made to closely fit the axle so asto prevent the entrance of dustinto the case.

In the drawing, Figure 1 is a perspective view, showing the dust-shieldand face-plate detached; and Fig. 2 is a longitudinal section, showingthe parts in proper position.

A is the box-case, having a groove, B, on each side to receive theguide-ribs of the pedestal. An the inner end of the case is a chamber,0, formed to receive a shield, D, preferably of wood, and having acircular orifice, E,

closely fitting the axle F. G is a face-plate, by which the shield isheld in place, the said plate having a beveled edge, f, fitting tightlyagainst the shoulder a of the case so as to exclude dust. The shield Dis free to move in all directions (but not to rotate) in the chamber O,and accommodates its position to the axle at all times, forming a secureprotection to the case A from the entrance of dust. The plate G issecured byscreW-bolts g.

I claim as my invention-- In a street-car axle-box, the movable shield Dhaving free play in the dust-chamber, and closely fitting on theaxle-spindle, in combination with the chamber 0 and face-plate G havingfree play on the axle, and provided with a beveled edge, f, fittingtightly against the shoulders a of the case, all arranged, constructed,and operated as set forth.
